Abstract
A color photographic silver halide material having a support, which material comprises at last one blue-sensitive, yellow-coupling silver halide emulsion layer and at least one green-sensitive, magenta-coupling silver halide emulsion layer and at least one red-sensitive, cyan-coupling silver halide emulsion layer, and which contains at least one masking coupler which has two chromophores which absorb in the wavelength range from 420 to 750 nm and are eliminable or decolorizable by coupling with the developer oxidation product, is distinguished by improved sensitivity associated with undiminished color purity.
